POCKET-LAMP FOR FIREABMS.

Specification of Letters Patent.

Patented Apr. 9, 1918 Application led April 23, 1914. Serial No.833,926.

To all whom t may concern.'

` Be it known that we, PAUL SCHMIDT and CARL DosLAw citizens of theGerman Empire, and residing at Berlin, Germany, have invented certainnew and useful Improvements in Pocket-Lamps for Firearms, of which thefollowing is a specication.

Our invention relates to electric pocket lamps, and a primary object isto provide an improved pocket lamp adapted to be detachably attached tothe barrels of smallarms, particularly small firearms such as pistols,and to be used as a device for lighting the target.

Our improved pocket lamp is of special value to watchmen, policemen andthe like who frequently have to enter dark rooms.

It is Well-known, for the purpose of aim ing accurately in the dark2 tomount on the weapon an illuminating aiming-tube which throws abrightly-illuminated mark of any desired form on the dark target. Suchilluminating tubes known heretofore have the defect, however, that ionthe one hand they are always ixedly mounted on the barrel, and on theother hand could not be used as ordinary lamps because the cone of lightwhich was emitted was too small to admit of a room being sulicientlyilluminated. Another obj ect of our invention is to obviate this defectby providing twoV lamps in one case or frame, one of which is providedwith a dispersion lens and the other with a system of condensin lensesof the type used in illuminating aiming tubes. Both lamps are fed by onebattery and can be connected into circuit either separately orconjointly.

In order to enable the lamp to be readily used on and ofi" the weapon alight sleeve is firmly attached from below to the barrel and is providedwith an attachment device, e. g. spring-pressed pins, by which the caseof the lamp can be readily and rapidly connected with the weapon.

To these ends, our invention consists in the construction, arrangementand combination of parts described hereinafter and pointed out in theclaims.

One illustrative embodiment of our invention and modifications ofdetails thereof are represented by way of example in the accompanyingdrawings, wherein:

Figure 1 is a side elevation from the lefthand showing our improved lampattached to an automatic pistol; Fig. 2 is a rea-r elevation of the lampand its attachment device, F ig. 3 is a like view after the end of thecase has been removed, and Figs. 4, 5 and 6 are bottom plan view, sideelevation and end elevation, respectively, showing the clamp forattaching the lamp;

Figs. 7, 8 and 9 are like views, respectively, showing a ymodified formof clamp for attaching the lamp to the pistol;

Fig. 10 is a side elevation of the lamp only as seen from the leftshowing the form of the upper connecting lug, Fig. 11 is a sectionthrough the aiming tube of the lamp, and Figs. 12 fand 13 are front andend elevations, respectively, of the battery;

Fig. 14 shows another form of lamp attached to a pistol, Figs. 15 and 16are side and end elevations, respectively, of the lamp only comprising arectangular battery and showing the attachment hook, and

Figs. 17, 18 and 19 are side elevation, end elevation and to plan viewshowing the clamp for attaching the lamp to the barrel.

Referrin to the drawings, a designates the case o the lamp in which theaiming tube c and the battery d are mounted. This case has a lateraltubular branch e containing an electric lamp and the dispersion lens g.The electric incandescent lamp 71. (Fig. 11) is mounted in the rear ofthe tube c and illuminates an aiming mark i by means of lenslt.` At thefront end of the tube c there is a condensing lens h which throws anenlarged image of the aiming mark z' on the object. This device isespecially adapted for use with lirearms as it performs the doublefunction of a pocket-lamp and an aiming-tube. The battery d has threecontact lugs k1, k2, lcs, the rst of which is connected with themetallic case of the lamp. The lamps are screwed into metallic holdersin the casing and are thus permanently electrically connected with thelug k. The

www@

two contact lugs or strips k2 and k3 are located a short distance fromthe end contact pieces of the lamps, so that these lugs can be pressedagainst these contact pieces by a slight pressure on the studs orbuttons Z, movable in the detachable cover fm of the ease, whereby thecircuits of the lamps are closed. The battery shown in Figs. 12 and 13comprises three cells arranged in such manner that the battery canpartially surround the tube c, as shown in Fig. 3.

On the `top of the casing is mounted a longitudinal piece of metal nhaving a lug 0 in front and recesses or holes p at the rear. The sleeveg has cheeks or lugs r, of a form corresponding to the member n,`between whose front ends is inserted a pin s, over which the lug otakes, while the springpressed pins t snap into the holes or recesses p.The sleeve g is held on the barrel either by the'lugs 'u or by thespring-pressed pins u (Figs. 7 to 9).

As shown in Figs. 111 to 16, in order to prevent the device slipping o'the barrel in consequence of severe vibration when firing a number ofshots in rapid succession, the casing a of the lamp is preferablyfastened by means of a small strip z having a hook m which takes intothe guard y of the trigger of the weapon.

As Figs. 17 to 19 show, the sleeve or clamp of the barrel may beprovided in front with a snap fw which can be folded backward over thesight of the weapon.
